How do I access cookies in a helper spec?

Question

I can't figure out how to test that a cookie has been set when testing my helper method.

Hypothetical helper method:

def my_helper(k,v)
    cookies[k] = v
end

Test:

it 'should set cookies' do  
  helper.my_helper("foo", "bar")
  helper.cookies["foo"].should == "bar" #nil
  helper.response.cookies["foo"].should == "bar" #nil
end

Anyone know how to do this?

I saw that post, as the OP mentions, he's still not sure how to _get_ cookies. — Matt Baker, Jul 25 '12 at 22:15
According to the rspec docs `response.cookies["foo"]` should work but I'm on rails 3.2 and rspec 2.8 and it does not work for me. https://www.relishapp.com/rspec/rspec-rails/docs/controller-specs/cookies. As far as I can tell there's something strange going on between rspec, rails integration tests, and rack which makes this hard to figure out. — Dty, Jul 26 '12 at 00:39

Substituting a simple rspec mock for the CookieJar works, if you're willing to:

helper.stubs(:cookies => cookies = mock)
cookies.expects(:[]=).with('foo', 'bar')
helper.my_helper('foo', 'bar')

I'm on rails 3.2 and rspec 2.8. Despite what the rspec docs says the following works for me in a request spec (ie. integration test).

it 'should set cookies' do  
  cookies['foo'] = 'bar'
  visit "/"
  cookies['foo'].should == 'bar'
end

Yup, I've definitely checked cookies in standard request specs. – Matt Baker Jul 26 '12 at 00:52
@MattBaker Which version of rails and rspec you're using? – Dty Jul 26 '12 at 00:59
@MattBaker also here an article about how someone debugged their way through using cookies in rspec. It might help you figure out how to troubleshoot this whole thing. http://dobbse.net/thinair/2011/12/capybara-racktest-rspec-cookies-2of2.html – Dty Jul 26 '12 at 01:01
We're on rails 3.1.4 and rspec 2.8. Maybe I'll take a shot at upgrading. – Matt Baker Jul 26 '12 at 01:13

request the cookie through

 helper.request.cookies[:awesome] = "something"

This doesn't work for me. Remember, I'm trying to _get_ the cookie, not set it. – Matt Baker Jul 25 '12 at 22:15
